The Anatomy corner💪
Scapula, Serratus, Oblique and Iliac crest none of which you see in my final drawing but they are all there 🙂 I like to think the flow of muscles (In my anatomy classes I call them Freeways). In this case from the Scapula (body landmark) to the Iliac crest (other body landmark). The serratus muscle starts from the inside of the scapula and reaches out grabbing the ribs, from there the Oblique muscle takes over reaching to the Iliac crest and in the front of the body merging with the abdominals muscles.
